    The purpose of the research was the study of the influence of a growing load on electric activity of biceps muscle of a shoulder. As the modelling movement the bending hands with a bar in cubital joints was used. The board behind the athlete, which did not allow him to use the muscle of a back at performance of exercise, was vertically installed. The researched lifted in modelling movement the maximal weight accepted as 100% after the special limbering up. The one rise of 90% weight from maximal followed after the rest. Further the athlete carried out 10 approaches to weight of 70 % from maximal. The changes of electroactivity of a biceps muscle of a shoulder consi-dered in the research allow to judge, that the load executed by athletes was directed on the development of power endurance. For its perfection 8, 9 and 10-th approaches have the greatest value.
